BOTTLE-CAPPING MACHINE.

Specification of Letters Patent. Patented Sept. 23, 1919.

Application filed August 8, 1916. Serial No. 113,726.

My invention relates to machines adapt-v ed to seal the mouths ofbottles by means of caps having corrugated rims. One of the objects ofmy invention is to provide a machine of this character with an improvedmeans for holding a bottle sealing cap; another' object is to provide animproved capping die adapted to force the rim of the cap over the lip ofthe bottle; a further object is to provide improved means for forcingthe bottle with the cap outwardly of the die.

lVith the above and related objects in view, my invention comprises theconstruction, combination and arrangement of parts, a practicalembodiment whereof is illustrated in the accompanying drawing andembraced within the scope of the appended claims.

In the said drawing Figure 1 is a side elevation of my machine; Fig. 2is a fragmentary vertical section thereof; Fig. 3 is an inverted plan ofmy improved mounting die and ejecting device, and Fig. 4 is a view of acap adapted to be mounted by means of my improved machine.

Referring more particularly to the drawing for a detail description ofmy invention 1 represents a pedestal, 2 represents its base which isslotted for clamping onto a table or bench, 3, 4 represents a wingedbolt adapted to clamp the base to said bench, 5 represents a bracketprovided with a vertical guide 6, and with a horizontal bearing 7 8represents a vertical rack movably supported by the guide 6, 9represents a platform mounted on top of the rack, 10 represents a shaftsupported by the bearing 7, 11 represents a gear mounted on the shaft inmesh with the rack 8, and 12 represents a lever for operating the gear.The pedestal is provided with a head 13, centrally above the platform 9.14 represents a cap holder provided with a horizontal opening forinserting a cap. The holder 14 is provided with a sleeve 15 extendedupwardly thereof and of a diameter larger than that of the holder andapproximately equal to that of the flange 13 of the head, whereby theholder is suspended from the head. The holder is provided with acontracted rim 16, adapted to support the rim of a cap. The rim 1G isthen expanded into a conical hood .17. The mounting die comprises ahollow cylinder 18 adapted to be projected through the bore of the headand is provided with perforated top above the. head and with a conicalrim 19 bearing against the bottom of the head, and a flange 2() isprojected downwardly of the rim. The flange 20 is in the form of twofrustums of cones having a common small circle. The flange 2O isslotted, said slots extending radially along the rim 19 to a distancewhere the solid unslotted portion of the rim is of a diameter equal t0the diameter of the small circle of the concs.

The ejector comprises a disk 21 provided with a perforated hub 22. Thedisk is countersunk to be flush with the head of a bolt 23 adapted tobeprojected through the perforated top of the cylinder 1S, theprojecting portion of the belt. being threaded for a nut. 24 adapted tosuspend the ejector under the rim 19 and within the small circle of theflange 20. Inside the cylinder 18 is mounted a spring coil wound on thebolt 23 between the top of the cylinder 1S and the top of the hubrepresents a cap mounted over the projecting portion of the cylinder 1S.

The cap shown in Fig. 4 comprises a circular top 2G, a fiange 27, and anexpanded corrugated rim 2S.

Having thus described my machine, it is operated as follows The bottle30, is mounted on the platform with its mouth centrally under theexpanded mouth 17 of the holder, a cap is inserted through the openingof the holder with its rim on top of the contracted rim 16 of theholder. The lever 12 is then forced downwardly to cause the gear to movethe rack 8 upwardly. The upward movement of the rack carries the bottlewith its mouth against the cap and forces the cap upwardly within thelower portion of the flange of the die. By exerting sufficient pressureupon the lever 12 the cap is forced through the small circle common tothe fiange 20, and the rim of the cap is forced by this contractedportion of the flange over the lip of the bottle, at the same time theejector holds the top of the cap flush against the mouth of the bottle.The'spider'legs formed by slotting the iiange and a portion of the rimof Y the die permits these legs to articulate VVslightly at the junctionwith the rim of the die. 'As the cap is forced through the small circleof the flange 20, the ejector is fo-rced upwardly against the bottom oflthe rim of the die, and its hub is forced within the cylinder 18 thuscompressing the spring. The lever is then moved inthe opposite di- Yrection, thus releasing the pressure on the ejector, the spring thenexpands, causing the ejector to' force the cap outwardly of the die. Theplatform can then be lowered by the further" downward movement of thelever until'the top of the bottle is below the holder, when it is freeto be removed. Y

That I claim as new and desire t0 protectby Letters Patent, is Y l. In acapping machine, a vertical bored head, a hollow `cylinder projectedthrough the bore of the head, lsaid Ycylinder eprovided with aperforated top above the head 'and witha conical rim below the headbearing against the bottom of the head, a flange extended downwardlyofthe rim, said iange comprising a pair of 'frustums of a cone having acommon small circle, said ange being divided into vertical sections byslots small and a large diameter and adished plate connecting them, thesmall 'diameter being. oriiiced for the reception olf-an' ejector andslots running longitudinally the full length of the large diameter andthrough part of the dished plate forming a resilientgmouth, theY largediameter being bent inwardly and then outwardly on al circle near itsopen end, the inner diameter ofsaid circle being'smaller than theVdiameterv of a bottle cap.

In testimony whereof I have signed this specification in the presence oftwo subp scribing witnesses. A
